The solar surface is the astrophysicist's best laboratory for the study of magnetoconvection. There exists equipartition of magnetic and kinetic energy. Higher up in the thin atmosphere of the solar corona, the gas is 'frozen' into the magnetic field

Doppler velocity observations obtained by the Global Oscillation Network Group (GONG) instruments directly measure the nearly steady flows in the solar photosphere. The sun's differential rotation is accurately determined from single observations. Th

Observed patterns of motion at the solar surface reflect the structure of subphotospheric convection, which controls the distribution of angular momentum and magnetic fields. Mesogranules are interpreted as secondary features associated with supergra

The Solar Optical Universal Polarimeter (SOUP) on Spacelab 2 collected time sequences of diffraction limited (0.5 are second) granulation images with excellent pointing (.003 arc seconds) and freedom from the distortion that plagues groundbased image

High-resolution measurements of magnetic fields have been made in quiet and active regions in order to determine whether the photospheric fine-structures (‘crinkles’), recently photographed by Dunn (1972), coincide with the footpoints of strong,

The evolution of the velocity and magnetic fields associated with supergranulation has been investigated using the Sacramento Peak Observatory Diode Array Magnetograph. The observations consist of time sequences of simultaneous velocity, magnetic fie

Known potential field solutions can be used to model the structure of magnetic fields in the solar photosphere. Several two-dimensional and axisymmetric solutions are compared. In the most satisfactory model the vertical component of the field is pre

The magnetic field in an axisymmetric pore is current free and can be represented by a flux tube with a magnetic potential of the formAJ0(kr)e-kz. For a given magnetic flux the field in this pore model is uniquely defined if the magnetic pressure bal

The strong magnetic fields observed between supergranules indicate that there must be subphotospheric convection in cells with a preferred diameter of about 30000 km. Orthodox mixing length theory assumes that the dimensions of cells are limited by t
